GHSA-v5gf-vpjc-pc7w: payload (CVE-2026-105866)

Package	Ecosystem	Affected	Fixed in
payload	npm	<3.90.0 \|\| >=4.0.0-canary.0, <4.0.0-canary.34	3.90.0, 4.0.0-canary.34

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Payload versions below 3.90.0, and 4.0.0-canary versions from 4.0.0-canary.0 up to (not including) 4.0.0-canary.34, are affected. An unauthenticated attacker who knows a user's email address or username can trigger the account lockout mechanism on an auth-enabled collection that uses local authentication, preventing that user from signing in. Upgrade the payload npm package to 3.90.0 or 4.0.0-canary.34 or later, where password resets clear the lockout state and the forgot-password flow enforces a minimum interval between reset emails.
